Dinosaur with protrusion from back of head

Parasaurolophus meaning "near crested lizard" in reference to Saurolophus is an extinct genus of ornithopod dinosaur from the Late Cretaceous Period]] of what is now North America, about million years ago. It was a herbivore that walked both as a biped and a quadruped. Three species are recognized: P.

Newly discovered dino with skull protrusion like "decorative fins on classic s cars" gets a name like a god and a car. Mercuriceratops gemini. It might sound like the home planet of a yet-to-be- introduced Marvel superhero, but in fact it's the moniker given to a new kind of dinosaur that has a swooping bony plate extending up behind its head. Evans is a co-author of a paper that describes the new species online in the journal Naturwissenschaften. The big beast -- which lived about 77 million years ago, weighed more than 2 tons, ate only plants, and was about 20 feet long -- belongs to the group of dinos known as ceratopsian, which is the horned class.

The type species , P. It lived during the Maastrichtian age of the Late Cretaceous period in what is now western North America. More complete fossils would come to be found in the following years. Pachycephalosaurus was among the last species of non-avian dinosaurs on Earth before the Cretaceous—Paleogene extinction event. The genus Tylosteus has been synonymized with Pachycephalosaurus , as have the genera Stygimoloch and Dracorex , in recent studies. Like other pachycephalosaurids, Pachycephalosaurus was a bipedal herbivore , possessing long, strong legs and somewhat small arms with five-fingered hands. This hypothesis has actually been highly disputed in recent years. Remains attributable to Pachycephalosaurus may have been found as early as the s. As determined by Donald Baird , in or , Ferdinand Vandeveer Hayden , an early fossil collector in the American West, collected a bone fragment in the vicinity of the head of the Missouri River , from what is now known to be the Lance Formation of southeastern Montana. Its actual nature was not revealed until Baird studied it again over a century later and identified it as a squamosal bone from the back of the skull of Pachycephalosaurus , including a set of bony knobs corresponding to those found on other specimens of Pachycephalosaurus. In , Baird successfully petitioned to have Pachycephalosaurus used instead of Tylosteus because the latter name had not been used for over fifty years, was based on undiagnostic materials, and had poor geographic and stratigraphic information. Gilmore in Gilmore assigned his new species to Troodon as T. Accordingly, what are now known as pachycephalosaurids were assigned to the family Troodontidae , a misconception which was not corrected until by Charles M. In , Barnum Brown and Erich Maren Schlaikjer , with newer, more complete material, established the genus Pachycephalosaurus.

Of all the dinosaurs, this one had the best chance of being a radio star. Called the Parasaurolophus, it was a duck-billed plant eater about the size of a pickup truck that had a unique characteristic — a large crest jutting from the back of its head that served as a horn. As part of the summer-long series Backyard Dinosaurs — which will feature a different dinosaur found in Alberta each week — University of Alberta paleontologist Scott Persons explained to the Homestretch how scientists came to that conclusion, and were even able to reproduce the sound it may have made. For our first backyard dinosaur, I want to talk about a critter called Parasaurolophus. It's a kind of duckbill or hadrosaur. So, it was a plant-eater, about the size of a big pickup truck.

The Pachycephalosaurus pronounced Pack — ee — sef — a-la — sore — us may not be as famous as the Pterodactyl or the T Rex , but this dinosaur has been a staple of pop culture for decades and has plenty that makes it stand out — most notably its unique dome shaped skull. This hard-headed creature lived in the late Cretaceous period about million years ago. They mostly roamed around North America, and are known by many simply as the dinosaur with the bump on its head. Want to know more about this head-butting, bipedal beast? Read on! The first Pachycephalosaurus fossil was found in by a man called Donald Baird who collected bone fragments around the Missouri River in Montana, America. However, it was nearly a century later when it was given its name in

Stubby horns over the eyes of Regaliceratops peterhewsi pictured in an artist's imagining reminded its discoverers of the comic book character Hellboy. A Triceratops cousin unearthed in Canada is so elaborately adorned "it blows your mind," one paleontologist says. Triceratops has a new cousin with a devilishly good nickname: "Hellboy. Paleontologists who excavated the fossil skull of the horned beast from a steep cliff in Canada had a hell of time chipping the pound kilogram specimen from the hard rock—hence its pet name. Only after freeing the fossil did the crew discover the moniker's pop culture connection. Though it had much smaller horns on its brow than its iconic cousin, the newfound dinosaur boasted a sizable horn on its snout and a fabulous frill on its head. The frill, or bony head protrusion, of Regaliceratops is so elaborate it "blows your mind," one scientist says. That crown of triangular bone spikes inspired its Latin scientific name : Regaliceratops peterhewski, the first word of which translates to "royal horned face," according to the study, published June 4 in the journal Current Biology. The second word is the name of the geologist who first spotted the fossil about a decade ago, Peter Hews.

Retrieved on January 20th, Assuming its genus classification is widely accepted, the appropriately named Titanoceratops would have been one of the largest ceratopsians, potentially reaching lengths of 25 feet from head to tail and weights in the neighborhood of five tons. Sauropod Dinosaur Pictures and Profiles. Pachycephalosaurus had a small muzzle that ended in a pointed beak. Large frill; two long horns over eyes. Temporal range: Late Cretaceous Campanian , Both of these ceratopsians horned, frilled dinosaurs were small, slender, unobtrusive plant-eaters with minimal frills, a far cry from "classic" members of the breed like Triceratops and Pentaceratops. The genus Tylosteus has been synonymized with Pachycephalosaurus , as have the genera Stygimoloch and Dracorex , in recent studies. The Dinosauria 2nd ed. Facts and Figures About Kosmoceratops. As a result of their bizarre head ornamentation, the skulls of ceratopsians tend to preserve better in the fossil record than the rest of their skeletons. Horns and Beaks: Ceratopsian and Ornithopod Dinosaurs.

The type species , P. It lived during the Maastrichtian age of the Late Cretaceous period in what is now western North America. More complete fossils would come to be found in the following years.

A partial cranial endocast for RAM was reconstructed from CT scan data, the first ever for a Parasaurolophus of any ontogenetic stage. PLOS Biology. In , Charles H. Meaning that Mercuriceraptops might just be the bony tip of fancy fossils yet to come. Parasaurolophus is among the most well-recognized dinosaurs, and is frequently portrayed in dinosaur-related television shows, movies, books, merchandise and other media. In Carpenter, Kenneth ed. As a proposed airlock, it would not have kept out water. Knight and in the Walt Disney animated film Fantasia. Subsequent dating of its fossil showed that Zuniceratops lived 10 million years before the bigger ceratopsians of the late Cretaceous period, such as Triceratops and Styracosaurus —making it the earliest known ceratopsian in North America.
